Hello Anu

Assuming you are using Ubuntu, go to "Software & Updates", then go to
"Additional Drivers", then try the options where the Graphics Cards/options
are listed (Xorg/NVIDIA/etc). Change to one that might be the suitable one
(or keep repeating this and next steps with other options listed if not
sure), hit "Apply Changes". Your VMD should work now, it did for me.

Regards
Sourav
